Volkswagen will introduce cylinder shut-off technology to its new 1.4-litre TSI engine from 2012.

VW is the first manufacturer to implement the fuel-saving technology in a mass-produced TSI engine, a system that shuts off two of the four cylinders under low to medium loads, between 1400 and 4000rpm.
